Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

As far as I've been able to find there is still no support for this device in the main kernel, any kmods, nor binaries from the manufacturer. I have tried Ubuntu 13.10, Fedora 18, and OpenSuse, and none of the other distros have packages for the card either. Here's some more information from my board, if it helps:
Laptop ASUS G75V
lspci - 03:00.0 Network controller: Broadcom Corporation Device 43b1 (rev 03) --just ask for more if you need it.
Cheers,

The problem seemed to be my lack of knowledge on how to load third party modules.
With more googling I found out that I only needed to run ""depmod -a" after the make install (this command should be included in the install target in the Makefile). After that I was able to successfully load the module with "modeprobe wl" and now the card WORKS!!

I don't see my network in the 5gh frequency, so I guess the module only supports the 2.4gh frequencies. Nevertheless, It's great to have the card working. I will use it in the next days and report any problems here.

What works: 2.4gh networks
What does not work yet: 5gh networks and bluetooth (which is provided by the same card)

I downloaded and compiled the 6_30_223_95 driver and it was built correctly. But to get it to work I had to copy it to another directory than that the "make install" command installed it.
cp wl.ko /lib/modules/3.8.0-26-generic/updates/dkms/

After a reboot it worked to connect to the 2.4GHz network.
I don't see my 5GHz network and no bluetooth icon in the top bar.

I tried ndiswrapper but it does not support all type of wifi authentication.
Driver seems to have a problem of timeout with wpa_supplicant when trying to authenticate with WPS AP
Other traditional AP works fine

That's why I build the native driver instead of use ndiswrapper.

My example : In France the Orange Livebox WPS AP authentication doesn't work (huge problem, Orange is the main provider)

However, I could not remove the existing wl module (using "sudo rmmod wl") because Ubuntu/Linux kept insisting that the wl module was in use. (This was the case even if I disabled wreless from the BIOS). I even tried "sudo rmmod --force wl", but it did not work. Nevertheless, I proceeded to install the new module and it worked after a reboot.

However, I want to point out that this also actually fixed a different bug in 3.8.0-27! I was unable to shutdown or restart the machine. It would just hang during the shutdown process. This is the bug: https://bugs.launchpad.net/ubuntu/+bug/1176028. After installing hybrid-v35_64-nodebug-pcoem-6_30_223_95, my computer shutdowns and restarts normally. I am mentioning this because the wireless fix (or something included in the fix) may be related to bug 1176028.

Just to confirm everything is workign smoothly, I did a fresh install of 13.04, updated all packages, and then aplied hybrid-v35_64-nodebug-pcoem-6_30_223_95. Both bugs #1173761 and #1176028 seem to be fixed.

I could only test Wireless 802.11n, since I do not have a 802.1ac network. Also, I can not verify if the 5Ghz or the 2.4GHz band is being utilized. Finally, Bluetooth, included with the Broadcom 43b1 device, still does not work.

This bug crashes the stock install process on Kubuntu. [something something 80211 "tainted module"] It was also causing long, or endless delays at startup and shutdown on Linux Mint 15 Olivia. I ended up disabling the chip in my bios and ordering a USB wifi antenna. I would appreciate a fix in the kernel on this one.

There's a newer driver on Broadcom's website. I highly recommend that over the driver linked here. It enables the 5ghz band. So all that's left is BT to be usable. You will still need the patch I linked to above if you are on 3.10.x or later.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

The fix for this bug has been awaiting testing feedback in the -proposed repository for trusty for more than 90 days. Please test this fix and update the bug appropriately with the results. In the event that the fix for this bug is still not verified 15 days from now, the package will be removed from the -proposed repository.

As part of a recent change in the Stable Release Update verification policy we would like to inform that for a bug to be considered verified for a given release a verification-done-$RELEASE tag needs to be added to the bug where $RELEASE is the name of the series the package that was tested (e.g. verification-done-xenial). Please note that the global 'verification-done' tag can no longer be used for this purpose.
